Try React

React has been designed from the start for gradual adoption, and you can use as little or as much React as you need. Whether you want to get a taste of React, add some interactivity to a simple HTML page, or start a complex React-powered app, the links in this section will help you get started.

Online Playgrounds

If you’re interested in playing around with React, you can use an online code playground. Try a Hello World template on CodePen or CodeSandbox.

If you prefer to use your own text editor, you can also download this HTML file, edit it, and open it from the local filesystem in your browser. It does a slow runtime code transformation, so we’d only recommend using this for simple demos.

Create a New React App

As your application grows, you might want to consider a more integrated setup. There are several JavaScript toolchains we recommend for larger applications. Each of them can work with little to no configuration and lets you take full advantage of the rich React ecosystem.

Learn React

People come to React from different backgrounds and with different learning styles. Whether you prefer a more theoretical or a practical approach, we hope you’ll find this section helpful.

Like any unfamiliar technology, React does have a learning curve. With practice and some patience, you will get the hang of it.

First Examples

The React homepage contains a few small React examples with a live editor. Even if you don’t know anything about React yet, try changing their code and see how it affects the result.

React for Beginners

If you feel that the React documentation goes at a faster pace than you’re comfortable with, check out this overview of React by Tania Rascia. It introduces the most important React concepts in a detailed, beginner-friendly way. Once you’re done, give the documentation another try!

React for Designers

If you’re coming from a design background, these resources are a great place to get started.

JavaScript Resources

The React documentation assumes some familiarity with programming in the JavaScript language. You don’t have to be an expert, but it’s harder to learn both React and JavaScript at the same time.

We recommend going through this JavaScript overview to check your knowledge level. It will take you between 30 minutes and an hour but you will feel more confident learning React.

Practical Tutorial

If you prefer to learn by doing, check out our practical tutorial. In this tutorial, we build a tic-tac-toe game in React. You might be tempted to skip it because you’re not building games — but give it a chance. The techniques you’ll learn in the tutorial are fundamental to building any React apps, and mastering it will give you a much deeper understanding.

Step-by-Step Guide

If you prefer to learn concepts step by step, our guide to main concepts is the best place to start. Every next chapter in it builds on the knowledge introduced in the previous chapters so you won’t miss anything as you go along.

Thinking in React

Many React users credit reading Thinking in React as the moment React finally “clicked” for them. It’s probably the oldest React walkthrough but it’s still just as relevant.

Advanced Concepts

Once you’re comfortable with the main concepts and played with React a little bit, you might be interested in more advanced topics. This section will introduce you to the powerful, but less commonly used React features like context and refs.

API Reference

This documentation section is useful when you want to learn more details about a particular React API. For example, React.Component API reference can provide you with details on how setState() works, and what different lifecycle methods are useful for.

Versioned Documentation

This documentation always reflects the latest stable version of React. Since React 16, you can find older versions of the documentation on a separate page. Note that documentation for past versions is snapshotted at the time of the release, and isn’t being continuously updated.
